(a) the link on the main screen seems to point to a completely different search engine, as compared to the one inside the Music Store itself

(b) every time I download a song I receive an activation key on my Nokia. Is this required? I called and talked to two different people at Vodafone, neither of whom could give me a definitive answer (the one in Egypt was particularly clueless). If I delete these activation keys will my downloaded music stop working or something? Or do I need to keep them forever?
